Final answer:
The intake valve is a component of the internal combustion engine that allows air and fuel mixture to enter the combustion chamber.
Step-by-step explanation:
The intake valve is a component of the internal combustion engine that is responsible for allowing air and fuel mixture to enter the combustion chamber.
During the intake stroke of the engine, the piston moves downward, creating a suction effect that draws the air and fuel mixture through the open intake valve into the cylinder.
Once the intake stroke is complete, the intake valve closes to seal the combustion chamber and prevent any air or fuel from escaping during the compression and power strokes of the engine.
